Booker says the man boarded a vacant American Airlines Airbus A321, which can seat up to 200 passengers. Florida Today reports the plane was blocked in to prevent movement. Two technicians doing work inside the plane confronted him and tackled him. One called police while the other subdued him. He was arrested within minutes.

Booker says the case is being investigated by the Joint Terrorism Task Force. They’re trying to determine a motive.
